The AIRAID 511-302 fits some Toyota 4 Runner, and Toyota FJ Cruiser models. See vehicle applications for details.
The AIRAID MXP Air Intake System represents the ultimate in AIRAID’s cold air induction systems and delivers higher levels of horsepower and acceleration gains for high-performance gas and diesel vehicles. Some AIRAID MXP Air Intakes start with a replacement one-piece roto-molded air box that addresses the shortcomings of the restrictive factory design. Housed inside the air box is an AIRAID premium air filter for outstanding air flow and filtration. Air is directed through a new air intake tube constructed of cross-linked, high-density polyethylene that is designed using extensive computer modeling to maintain proper mass air flow readings and calibration. Many MXP Air Intake Systems have a built-in velocity stack, which further promotes airflow. What this all means is that you get a simple-to-install, yet extremely sophisticated system to increase air flow while maintaining proper air-to-fuel ratios, thereby eliminating the need for recalibration after installation. Just bolt it on and go! Some AIRAID air intakes are not legal for sale or use in California and other states adopting California emission standards, while others are 50 state legal. View the product's vehicle applications to determine the legal status for each vehicle.

LOVE the way this sounds. A throaty Grrrrrrr....especially during acceleration. Speaking of which, there is definitely some noticeable improvement in acceleration, but no measured difference in gas mileage.

I recently installed an MXP cold air intake on my 2012 FJ Cruiser. Installation was very easy and the instructions were first class. This system improved throttle response as advertised. It's a little louder than the stock TRD cold air intake but the increased sound is not objectionable (in fact, I like it). Haven't noticed any increase in fuel economy but with a 4x4 SUV I didn't have any real expectations in that area anyway. The installation looks great and the mod needed to the plastic engine cover was minimal and easy to do. I'm very happy with the quality of materials used and impressed with the exceptional engineering that went into the design of this product. Congratulations to Airaid for combining with K&N. Both are great organizations, offering superior products.

The intake system is absolutely fantastic, it made a big difference while accelerating. However, the package was in very bad condition due to poor shipping.
